The lottery initiative is sponsored by Salem attorney Kevin Mannix, an unsuccessful Republican candidate for governor and attorney general. Mannix also is the sponsor of an initiative that has qualified for the ballot that would impose mandatory, minimum sentences for certain first-time drug offenses and property crimes.

Under current law, about two-thirds of lottery revenues are used for education, 15 percent is dedicated to parks and natural resources and 17 percent to economic development. Because the 15 percent diversion to public safety almost certainly would come from money that now goes to schools, the measure is likely to be opposed by education advocates.

The other initiative would create an "open primary" election system in the state. It is sponsored by two former secretaries of state, Democrat Phil Keisling and Republican Norma Paulus.

Under this measure, all candidates for a political office would run in a single primary election, which would be open to all voters, regardless of party registration. The top two vote-getters, regardless of party affiliation, would advance to the general election.

The measure is opposed by leaders of both the Democratic and Republican parties and minor parties, who fear the system would lock their candidates out of the general election. Keisling argues that an open primary would boost voter turnout and reduce partisanship in state politics.

Elections Division officials said that 75.4 percent of the voter signatures submitted to put the open primary initiative on the ballot were valid, the highest validity rate for any initiative this year. The lottery revenue initiative had a signature validity rate of 64.4 percent.

So far, seven initiatives have qualified for the November ballot. One other initiative, sponsored by anti-tax activist Bill Sizemore, is still being processed by the Elections Division. It would eliminate seniority as a factor in determining public school teachers' salaries and job security.

In addition to the initiatives, the November ballot will include four measures referred to voters by the Legislature. They include one that the Legislature passed as an alternative to Mannix's mandatory minimum sentencing measure.
